热力图

热力图除了百度地图api外,还需单独引入一个js
   <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=K8Tbhgiqnye40mNodYv9ox8i"></script>
 1 <script type="text/javascript" src="http://api.map.baidu.com/library/Heatmap/2.0/src/Heatmap_min.js"></script>

//组织数据
for(var i=0;i<infoArray.length;i++){
                            var info = infoArray[i];
//                            console.log(info);
                            var pt = {"lng":info.lng,"lat":info.lat,"count":info.billMoney};　　//count 权重
                            points.push(pt);
                            
                            mapPanel.points.push(info);
                        }
                        view.showReli(500000,points,map);

显示热力图

showReli:function(maxCount,points,map){
        var heatmapOverlay = new BMapLib.HeatmapOverlay({"radius":30,"visible":true, "opacity":70});
        map.addOverlay(heatmapOverlay);
        heatmapOverlay.setDataSet({'data':points,'max':maxCount});　　//最大权重值:maxCount
    }
